Episode 33 – The Importance Of Breaking Things

Conventional wisdom tells us that a network that never breaks is the most resilient, but practice tells us otherwise. In this episode we explore the value of chaos engineering and how breaking your network intentionally can make it stronger.

Reality Check: Self-Driving Networks

I stumbled upon an article with an interesting title (and worth reading): To Make Self-Driving Cars Safe, We Also Need Better Roads and Infrastructure… and thought about the claims along the lines of “if they managed to solve the self-driving cars challenge, it’s realistic to expect self-driving networks” made in Self-Driving Networks podcast episode. Turns out the self-driving cars problem is far far away from being solved.

AfPIF 2018 Kicks Off

The ninth edition of Africa Peering and Interconnection Forum (AfPIF) kicked off today, with more than 400 tech executive in attendance.

This year, the forum was organized and held jointly with iWeek- South Africa ISP Association’s premier tech event. The event is underway at the Cape Town International Convention Center.

This year’s event is dubbed AfPIF@iWeek has attracted tech executives, chief technology officers, peering coordinators and business development managers, Internet service providers and operators, telecommunications policymakers and regulators, content providers, Internet Exchange Point (IXP) operators, infrastructure providers, data center managers, National Research and Education Networks (NRENs), carriers, and transit providers.

The sessions started with an introduction by Nishal Goburdhan, a veteran of AfPIF, who traced the history of AfPIF, from its conception to the community event it is. The community took over the program three years ago, determining the speakers and the conference content.

How can you take advantage of AfPIF? Nishal suggested that the participants use peering personals sessions; this is like speed dating for networks – members give details of their AS numbers, where they peer, peering policy, contact information, and explain why other participants should peer with them. At the end of every session, participants get a Continue reading

Refresh Stale DNS Records on 1.1.1.1

Refresh Stale DNS Records on 1.1.1.1

You can now refresh 1.1.1.1’s DNS cache for domain names by using the purge cache tool. This is useful for domain owners who have updated their DNS records and want to make sure it is reflected for people who are using 1.1.1.1 as their public DNS resolver.

Refresh Stale DNS Records on 1.1.1.1

When a client queries for a domain against 1.1.1.1, the resolver returns the IP address from its cache. The cache TTL for a DNS entry is 3 hours. If the host specifies a cache TTL that is shorter than 3 hours, the resolver respects that. This means, when a domain owner changes the DNS host from one to another, in the worst case, she will have to wait for at least 3 hours before the old IP address expires from 1.1.1.1’s cache. With the help of the purge cache tool, a domain owner can now easily refresh 1.1.1.1’s DNS cache and will not have to wait for the cached entry to expire.

Refresh Stale DNS Records on 1.1.1.1

To purge a DNS record, you enter the name of your domain, pick the DNS record type and hit the ‘Purge Cache’ button.

How we chose the 10 AI-powered startups to watch

The selection process for this roundup started back in May at the tail-end of a previous, but closely related competition, 10 Hot IoT startups to watch.AI wasn’t a key selection criterion then. Some startups had it, some did not, but enough of them focused squarely on AI that it made sense to look more closely at this subsector of the overall IoT market.[ Check out our corporate guide to addressing IoT security. ] This roundup considered about 20 companies from the previous contenders that had strong AI components. Notice of the search for candidates was posted on HARO, LinkedIn, Twitter, etc., and all told, just under 40 startups were considered.To read this article in full, please click here

10 Hot AI-powered IoT startups

Plants, factories, and manufacturers in general are embracing IoT, which in turn is driving the use of artificial intelligence at the edge of corporate networks as a way to streamline industrial processes, improve efficiency and detect maintenance issues before they become problems – perhaps even big problems that could force plant shutdowns.To read this article in full, please click here(Insider Story)

BrandPost: Multi-Layer Networks? Intelligent Multi-Layer Orchestration Has Arrived

Kailem Anderson, Vice President of Product Management for Software and Services, Ciena There are many challenges that service providers must deal with in multi-layer networks. A majority of them stem from the lack of coordinated visibility and orchestration across the optical and IP/MPLS layers. Ciena’s Kailem Anderson details these challenges and the benefits that multi-layer orchestration can bring.

BrandPost: Why Smart Cities Need Adaptable Pipes

Daniele Loffreda, Senior Advisor, Industry Marketing For cities to evolve and realize the full benefits of becoming “smart,” they will require real-time access to multiple sources of data from different locations. Ciena’s Daniele Loffreda explains what is needed from the next-generation of networks to make smart cities a reality.Apple CEO, Tim Cook, said it best during a commencement address at the prestigious Massachusetts Institute of Technology (MIT) last year when he proclaimed science and technology are worthless, if they aren’t motivated by the desire to help people. This belief can be just as correctly applied to the planning and development of smart city initiatives.To read this article in full, please click here

Internet Native Applications

Internet Native Applications

I grew up with DOS and Windows 3.1. I remember applications being fast - instant feedback or close to it. Today, native applications like Outlook or Apple Mail still feel fast - click compose and the window is there instantly and it feels snappy. Internet applications do not.

My first Internet experience was paying $30 for a prepaid card with 10 hour access over a 14.4k modem. First, it was bulletin boards and later IRC and the WWW. From my small seaside town in Australia, the Internet was a window into the wider world, but it was slooooooow. In a way, it didn’t matter. The world of opportunities the Internet opened up, from information to music, to socializing and ecommerce, who cared if it was slow? The utility of the Internet and Internet applications meant I would use them regardless of the experience.

Performance improved from the 90s, but in 2008 when I switched from Outlook downloading my Yahoo! email over IMAP to Gmail in the browser, it wasn’t because it was faster - it wasn’t - it was because features like search, backed up mail, and unlimited storage were too good to resist. The cloud computing power Continue reading

Integrating redirection.io with Cloudflare Workers

Integrating redirection.io with Cloudflare Workers

The following is a guest post by Xavier Lacot, a developer at redirection.io and founder at JoliCode. He works primarily on Web and mobile projects as a consultant, trainer and technical expert.

What is redirection.io

Redirection.io is a Web traffic redirection manager. It provides a collection of tools for website administrators, SEO agencies, and developers, which help analyze HTTP errors, setup HTTP redirections, customize HTTP responses, and monitor the traffic efficiently.

The main part of a traditional redirection.io setup is the proxy, a software component which parses every request to check if a redirection or another response override is required. This "proxy" can be of several types - we provide libraries in several languages - but this setup can be simplified for Cloudflare clients by taking advantage of Cloudflare Workers.

Here come Cloudflare Workers

Earlier this year, Cloudflare unveiled its Workers product, a smart way of running code on the edge of Cloudflare locations. This computing feature is particularly interesting, as it allows performing several traffic operations without requiring any change on your own platform, code, or infrastructure: just enable Workers, write some code, and let Cloudflare handle the magic ✨

In practical terms, Workers Continue reading

DHCP defined and how it works

The ability to network devices quickly and easily is critical in a hyper-connected world, and although it has been around for decades, DHCP remains an essential method to ensure that devices are able to join networks and are configured correctly. DHCP greatly reduces the errors that are made when IP addresses are assigned manually, and can stretch IP addresses by limiting how long a device can keep an individual IP address. [ Now read 20 hot jobs ambitious IT pros should shoot for. ] DHCP definition DHCP stands for dynamic host configuration protocol and is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints.To read this article in full, please click here
